Regional aspects of Miami crime fiction

This thesis argues that forces of literary regionalism and postmodern culture are behind the explosion of crime fiction being written in and about South Florida by a growing number of resident authors. Research included four methods of investigation: 1. A critical reading of many of the novels that make up the sub-genre. 2. A study of the theories of regionalism, postmodernism and the genre of the crime fiction. 3. Interviews with a number of the authors and a prominent Miami book seller. 4. Sociological studies of Miami in terms of historical events and their cultural significance. Today's South Florida crime fiction authors cast their narratives in the old genre of the detective novel where characters are delineated according to traditional definitions of good and evil. Evil characters threaten established order. What makes South Florida crime fiction different from traditional detective fiction is its interest in the exotic, postmodern culture and setting of South Florida. Like the region, the villains are exotic and the order that they threaten is postmodern. There is less of an interest in attributing a larger social meaning to the heroes. Rather, there is an ontological interest in the playing out of good against evil in an almost mythical setting that magnifies economic, environmental and racial issues. There is a unique cultural diversity of the city due to the geographical location of Miami in relationship to Latin America and the Caribbean, and the political forces at work in the region. South Florida's subtropical climate, fragile ecosystem, and elements of frontier life in a cosmopolitan city work to support Miami crime fiction. The setting personifies the unpredictability and pastiche of a postmodern world and may call for a new definition for literature that relies on non-traditional regional characteristics.

This was uncalled for : Dave Eggers' A heartbreaking work of staggering genius subverts the genre of traditional autobiography as an attempt at rendering his life

The purpose of this thesis was to explore why and how the author Dave Eggers subverts the genre of traditional autobiography in his memoir A Heartbreaking Work of Staggering Genius. I compared Eggers' work to Gertrude Stein's The Autobiography of Alice B. Toklas and William S. Burroughs' Junky. I found that like Stein and Burroughs, Eggers utilized various rhetorical devices outside of traditional autobiography because he could not find the means to express himself within the genre. Eggers employed various rhetorical methods reserved for fictional texts, such as stream of consciousness, characterization, and irony, in order to reconcile his feelings towards his parents' deaths and render those feelings in his memoir. I established that Eggers concluded his memoir with impossibility of arriving at one Meaning that could summate his tragic experience. Thus, I proved that Eggers gave the reader the only authentic interpretation he could: the memoir as a small, incomplete glimpse into his life.

Lattice boltzmann modeling of fluid flow to determine the permeability of a karst specimen

A limestone sample was scanned using computed tomography (CT) and the hydraulic conductivity of the 3D reconstructed sample was determined using Lattice- Boltzmann methods (LBM) at varying scales. Due to the shape and size of the original sample, it was challenging to obtain a consistent rectilinear test sample. Through visual inspection however, 91 mm and 76 mm samples were digitally cut from the original. The samples had porosities of 58% and 64% and produced hydraulic conductivity values of K= 13.5 m/s and K=34.5 m/s, respectively. Both of these samples were re-sampled to 1/8 and 1/64 of their original size to produce new virtual samples at lower resolutions of 0.542 mm/lu and 1.084 mm/lu, while still representing the same physical dimensions. The hydraulic conductivity tended to increase slightly as the resolution became coarser. In order to determine an REV, the 91 mm sample was also sub-sampled into blocks that were 1/8 and 1/64 the size of the original. The results were consistent with analytical expectations such as those produced by the Kozeny-Carman equation. A definitive REV size was not reached, however, indicating the need for a larger sample. The methods described here demonstrate the ability of LBM to test rock structures and sizes not normally attainable.

Dynamic job quoting system for printed circuit board fabrication

This research deals with the development of a dynamic job quotation system for printed circuit board (PCB) fabrication, which can estimate the price and completion time of a job based on customer preference and current capacity of the shop floor. The primary purpose of building a dynamic quotation system is to maximize the company's profit by quoting optimum lead-time and competitive price for the day-to-day orders received from different customers and original equipment manufacturers. The system was developed using MS-Access relational database. Evaluating the output of the system it was observed that the dynamic system provided more reliable estimation of the lead-time needed for fabricating new jobs. The overall price quoted by the system was competitive with higher profit margin when compared to traditional static systems. This system would therefore provide a vital link between the job quoting and scheduling system of the firm enabling better utilization of the available resources.

A realtime internet based quality control application for hurricane surface wind observations

This thesis chronicles the design and implementation of a Intemet/Intranet and database based application for the quality control of hurricane surface wind observations. A quality control session consists of selecting desired observation types to be viewed and determining a storm track based time window for viewing the data. All observations of the selected types are then plotted in a storm relative view for the chosen time window and geography is positioned for the storm-center time about which an objective analysis can be performed. Users then make decisions about data validity through visual nearestneighbor comparison and inspection. The project employed an Object Oriented iterative development method from beginning to end and its implementation primarily features the Java programming language.

Implicit metaphysis of the Visuddhimagga : assāsa-passāsa as a vital animating force

This research examines how assasa-passisa and its surrounding concepts are discussed in Buddhaghossa's 5th century Theravada work, the Visuddhimagga (The Path of Purification) to determine if there is metaphysical use of the term in the text and to determine if the concept of assasa-passasa is similar to the better-known Indian concept of prana (metaphysical vital animating force), indicating whether Theravada Buddhism more closely resembles other Indian religions in terms of metaphysical content. Text analysis reveals how assasa-passasa is described in the Visuddhimagga as an animating vital force, suggesting that Theravada Buddhism has an implicit ontology similar to other Indian schools of philosophy. Secondarily, this paper argues that because assisa-passasa plays a similar role to prana in the Visuddhimagga, it is also operationally similar and could be functioning as the implicit intermediary between links in the chain of dependent co-arising-as the vehicle of paticcasamuppada.

Developing brownfields ranking models using decision analytic methods

The redevelopment of Brownfields has taken off in the 1990s, supported by federal and state incentives, and largely accomplished by local initiatives. Brownfields redevelopment has several associated benefits. These include the revitalization of inner-city neighborhoods, creation of jobs, stimulation of tax revenues, greater protection of public health and natural resources, the renewal and reuse existing civil infrastructure and Greenfields protection. While these benefits are numerous, the obstacles to Brownfields redevelopment are also very much alive. Redevelopment issues typically embrace a host of financial and legal liability concerns, technical and economic constraints, competing objectives, and uncertainties arising from inadequate site information. Because the resources for Brownfields redevelopment are usually limited, local programs will require creativity in addressing these existing obstacles in a manner that extends their limited resources for returning Brownfields to productive uses. Such programs may benefit from a structured and defensible decision framework to prioritize sites for redevelopment: one that incorporates the desired objectives, corresponding variables and uncertainties associated with Brownfields redevelopment. This thesis demonstrates the use of a decision analytic tool, Bayesian Influence Diagrams, and related decision analytic tools in developing quantitative decision models to evaluate and rank Brownfields sites on the basis of their redevelopment potential.

An Investigation on Biocompatibility of Bio-Absorbable Polymer Coated Magnesium Alloys

Advances in biomaterials have enabled medical practitioners to replace diseased body parts or to assist in the healing process. In situations where a permanent biomaterial implant is used for a temporary application, additional surgeries are required to remove these implants once the healing process is complete, which increases medical costs and patient morbidity. Bio-absorbable materials dissolve and are metabolized by the body after the healing process is complete thereby negating additional surgeries for removal of implants. Magnesium alloys as novel bio-absorbable biomaterials, have attracted great attention recently because of their good mechanical properties, biocompatibility and corrosion rate in physiological environments. However, usage of Mg as biodegradable implant has been limited by its poor corrosion resistance in the physiological solutions. An optimal biodegradable implant must initially have slow degradation to ensure total mechanical integrity then degrade over time as the tissue heals. The current research focuses on surface modification of Mg alloy (MZC) by surface treatment and polymer coating in an effort to enhance the corrosion rate and biocompatibility. It is envisaged that the results obtained from this investigation would provide the academic community with insights for the utilization of bio-absorbable implants particularly for patients suffering from atherosclerosis. The alloying elements used in this study are zinc and calcium both of which are essential minerals in the human metabolic and healing processes. A hydrophobic biodegradable co-polymer, polyglycolic-co-caprolactone (PGCL), was used to coat the surface treated MZC to retard the initial degradation rate. Two surface treatments were selected: (a) acid etching and (b) anodization to produce different surface morphologies, roughness, surface energy, chemistry and hydrophobicity that are pivotal for PGCL adhesion onto the MZC. Additionally, analyses of biodegradation, biocompatibility, and mechanical integrity were performed in order to investigate the optimum surface modification process, suitable for biomaterial implants. The study concluded that anodization created better adhesion between the MZC and PGCL coating. Furthermore, PGCL coated anodized MZC exhibited lower corrosion rate, good mechanical integrity, and better biocompatibility as compared with acid etched.

The creation of Huey P. Newton

The purpose of this study was to examine the creation of Huey P. Newton, founder of the Black Panther Party in 1966. I argued that Huey P. Newton was a creation of several elements: the black ghetto of Oakland; the rise of Black Power and the death of non-violence in the civil rights movement; the New Left and its factions; and, the Black Panther Party through the "Free Huey" campaign. The "Free Huey" campaign that arose from Newton's imprisonment in 1968, constructed an iconic image of Newton that he inherited on his release in 1970. This study will contextualize Newton and refute the claims of Hugh Pearson, author of the 1994, The Shadow of the Panther, who deemed Newton as a common criminal, not worthy of historical debate.

A Cultural Historical Study of Land Use in Dade County, Florida

Humans have used the land within the area currently defined as Dade County, Florida since around 11,000 B.P., but did not significantly alter the local environment until less than one hundred years ago. These recent changes greatly affected many critical ecological factors, thereby reducing the sustainability of many types of life, including humans. This study explains how land use evolved from earlier sustainable systems for satisfying human needs into the current menacing patterns. This is done by examining the environmental, technological, social, and cognitive contexts of land use through time. Changes in all these areas have followed a general trend leading to increasing intensity of land use and environmental change driven by population growth and technological innovation.

The Structure of Games

Computer Game Playing has been an active area of research since Samuel’s first Checkers player (Samuel 1959). Recently interest beyond the classic games of Chess and Checkers has led to competitions such as the General Game Playing competition, in which players have no beforehand knowledge of the games they are to play, and the Computer Poker Competition which force players to reason about imperfect information under conditions of uncertainty. The purpose of this dissertation is to explore the area of General Game Playing both specifically and generally. On the specific side, we describe the design and implementation of our General Game Playing system OGRE. This system includes an innovative method for feature extraction that helped it to achieve second and fourth place in two international General Game Playing competitions. On the more general side, we also introduce the Regular Game Language, which goes beyond current works to provide support for both stochastic and imperfect information games as well as the more traditional games.

Adaptive Fault-Tolerant Teleoperation

While the robots gradually become a part of our daily lives, they already play vital roles in many critical operations. Some of these critical tasks include surgeries, battlefield operations, and tasks that take place in hazardous environments or distant locations such as space missions. In most of these tasks, remotely controlled robots are used instead of autonomous robots. This special area of robotics is called teleoperation. Teleoperation systems must be reliable when used in critical tasks; hence, all of the subsystems must be dependable even under a subsystem or communication line failure. These systems are categorized as unilateral or bilateral teleoperation. A special type of bilateral teleoperation is described as force-reflecting teleoperation, which is further investigated as limited- and unlimited-workspace teleoperation. Teleoperation systems configured in this study are tested both in numerical simulations and experiments. A new method, Virtual Rapid Robot Prototyping, is introduced to create system models rapidly and accurately. This method is then extended to configure experimental setups with actual master systems working with system models of the slave robots accompanied with virtual reality screens as well as the actual slaves. Fault-tolerant design and modeling of the master and slave systems are also addressed at different levels to prevent subsystem failure. Teleoperation controllers are designed to compensate for instabilities due to communication time delays. Modifications to the existing controllers are proposed to configure a controller that is reliable in communication line failures. Position/force controllers are also introduced for master and/or slave robots. Later, controller architecture changes are discussed in order to make these controllers dependable even in systems experiencing communication problems. The customary and proposed controllers for teleoperation systems are tested in numerical simulations on single- and multi-DOF teleoperation systems. Experimental studies are then conducted on seven different systems that included limited- and unlimited-workspace teleoperation to verify and improve simulation studies. Experiments of the proposed controllers were successful relative to the customary controllers. Overall, by employing the fault-tolerance features and the proposed controllers, a more reliable teleoperation system is possible to design and configure which allows these systems to be used in a wider range of critical missions.

A Static Traffic Assignment Model Combined with an Artificial Neural Network Delay Model

As traffic congestion continues to worsen in large urban areas, solutions are urgently sought. However, transportation planning models, which estimate traffic volumes on transportation network links, are often unable to realistically consider travel time delays at intersections. Introducing signal controls in models often result in significant and unstable changes in network attributes, which, in turn, leads to instability of models. Ignoring the effect of delays at intersections makes the model output inaccurate and unable to predict travel time. To represent traffic conditions in a network more accurately, planning models should be capable of arriving at a network solution based on travel costs that are consistent with the intersection delays due to signal controls. This research attempts to achieve this goal by optimizing signal controls and estimating intersection delays accordingly, which are then used in traffic assignment. Simultaneous optimization of traffic routing and signal controls has not been accomplished in real-world applications of traffic assignment. To this end, a delay model dealing with five major types of intersections has been developed using artificial neural networks (ANNs). An ANN architecture consists of interconnecting artificial neurons. The architecture may either be used to gain an understanding of biological neural networks, or for solving artificial intelligence problems without necessarily creating a model of a real biological system. The ANN delay model has been trained using extensive simulations based on TRANSYT-7F signal optimizations. The delay estimates by the ANN delay model have percentage root-mean-squared errors (%RMSE) that are less than 25.6%, which is satisfactory for planning purposes. Larger prediction errors are typically associated with severely oversaturated conditions. A combined system has also been developed that includes the artificial neural network (ANN) delay estimating model and a user-equilibrium (UE) traffic assignment model. The combined system employs the Frank-Wolfe method to achieve a convergent solution. Because the ANN delay model provides no derivatives of the delay function, a Mesh Adaptive Direct Search (MADS) method is applied to assist in and expedite the iterative process of the Frank-Wolfe method. The performance of the combined system confirms that the convergence of the solution is achieved, although the global optimum may not be guaranteed.

A Study of Teachers' Espoused Instructional Beliefs

The purpose of this study was to investigate teachers’ espoused instructional beliefs and whether they differed in relation to schools’ socioeconomic status, extent of teachers’ educational background, or extent of teachers’ classroom experience. The study comprised a total of 242 Miami-Dade County public school educators who responded to a thirty-nine question Likert scale, Literacy Instructional Practices Questionnaire. Eighteen schools, three from each of the six regions, were purposively selected based on the socioeconomic status of students. Nine participants were interviewed using semi-standardized interview procedures and open-ended questioning techniques. Multivariate Analysis of Variance (MANOVA) results revealed that teachers’ espoused beliefs concerning the instruction of literacy and forces and influences affecting instruction do not significantly differ depending on schools’ socioeconomic status, extent of teachers’ educational background, or extent of teachers’ classroom experience. The majority of teachers appear to follow a top-down generated direct instruction model. Generally, students are taught as a whole class and ability grouped for specific skill instruction utilizing commercially produced reading and language arts texts. There was no evidence of a relationship between teachers’ espoused beliefs concerning the model of instruction that they practice or teachers’ espoused beliefs concerning research and its application to practice and the three independent variables. Interview data corroborated much of the information garnered through the questionnaire. However, interview participants espoused the belief that research did not influence their selection of instructional practices. Although teachers perceive of themselves as eclectic in their espoused instructional beliefs, they appear to follow a skills based direct instruction pedagogy in practice. Much of what teachers believe constitutes effective practice, few researchers recommend, affirming the findings of Calderhead (1993) and the National Educational Research Policy and Priorities Board (U.S. Department of Education, 1998, p. 18) that “educators rarely know research, seek it out, or act in accordance with its results.”
